RE: one more point, those who defend the 39 book OT canon point to the Jews and say it is the canon they accept. true enough, but these are the same Jews that Jesus declared to be spiritually blind.
I’ mot sure we can use this as proof that the Jewish leaders of Jesus’ time (i.e. the Pharisees ) were using the wrong scripture or Canon.
Jesus DID tell the people to LISTEN to the teachings of the Pharisees, not to follow their hypocritical ways.
MATTHEW 23:1-3
“The scribes and the Pharisees sit on Moses’ seat, so DO and OBSERVE WHATEVER THEY TELL YOU, but not the works they do. For they preach, but do not practice.”
please read Acts 5:21-32. Once the Church was established and the Holy Spirit poured out, the seat of Moses ceased to exist. Actually, the seat of Moses was a type of the Church.
Hopefully you would not follow the present day Pharisees if they commanded you not to believe in Jesus Christ.
